Abstract:
The paper describes practical approach to implementation of satellite data archive using Globus Toolkit
4 components. The solutions consists in converting a hierarchy of remote data files available via FTP into Grid-
enabled archive. All etries of such archive will be indexed using arbitrary but pre-defined XML schema. The
information will be exposed via MDS4 Index service and the actual data will be exposed via GridFTP. The
schema used in our solution is simple enough for understanding but in a real life applications we should use
metadata standards such as ISO 19139 and ISO 19115 in particular. A working prototype of the archive
described in this paper is deployed on the Grid testbed of Space Research Institute of National Academy of
Science and National Space Agency of Ukraine (SRI-NASU-NSAU). The SRI-NASU-NSAU testbed is briefly
described in this paper as well.
